(FORTUNE Magazine) – than Antarctica ADDIS ABABA, Ethiopia -- The 21st meeting of the Organization of African Unity ended . . . a day earlier than planned. The African leaders spent Friday night reviewing draft resolutions on topics as disparate as the right to exploit Antarctica, the composition of an African anthem, African-Arab cooperation, and the fight against rinderpest, a disease afflicting cattle . . . One organization statement distributed today cited the ''burning issue'' of the failure of member nations to pay their dues. Only three of the 51 members are not in arrears. -- From a news report in the New York Times.
